For ease of understanding, components other than those necessary for explanation is omitted from the illustration as appropriate.

(1) Overall Structure of Booth

FIG. 1 is a relevant-part perspective view illustrating the internal structure of a booth 1 according to this exemplary embodiment, and FIG. 2 is a plan view illustrating how the booth 1 is installed. The overall structure of the booth 1 will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the booth 1 has a box shape overall. A desk 11, a chair 12, a monitor 13, a lighting fixture 14, an electrical-equipment box 15, and an air-conditioner indoor unit 16 are installed in the booth 1, and an air-conditioner outdoor unit 17 is installed on a side of the booth 1. A user can do activities such as working, studying, etc., in an air-conditioned space formed inside the booth 1 while sitting on the chair 12 and using the desk 11 and the monitor 13. Alternatively, the user can receive an on-line service over a telecommunication line.

The booth 1 includes a base 2 provided on an installation surface FL, a floorboard 3 provided on the base 2, side-wall panels 4 installed upright on the base 2, a ceiling panel 5 provided on the side-wall panels 4, and caster wheels 6 (see FIGS. 3A and 3B) provided below the base 2.

The base 2 is formed of four joists joined to form a rectangular shape corresponding to the shape of the bottom of the booth 1 and is formed of, for example, rectangular steel tubes.

The floorboard 3 is in contact with and is supported by a floor support member 2 a provided so as to project to the inside of the base 2 and includes, for example, a structural plywood, which is a wood board, and a floor mat laid thereon.

The side-wall panels 4 include: a first side-wall panel 41, which constitutes a far-side wall; a second side-wall panel 42, which constitutes a left wall; a third side-wall panel 43, which constitutes a right wall; and a fourth side-wall panel 44, which constitutes a near-side wall. The fourth side-wall panel 44 has an opening 44 a serving as a doorway, to which a door 45 is attached. In this exemplary embodiment, the door 45 is a sliding door.

The ceiling panel 5 is fixed to the upper end of the side-wall panels 4 so as to close the opening defined by the side-wall panels 4. The ceiling panel 5 is formed of, for example, a structural plywood, which is a wood board.

The caster wheels 6 are provided at four corners below the base 2. When a booth 1 assembled in a factory or the like is to be installed in an installation site, the booth 1 is transported by a truck or the like and, when installed on the installation surface FL at the installation site, the booth 1 is moved by using the caster wheels 6.

Inside the booth 1, the desk 11 is disposed on the floorboard 3 so as to be in contact with the third side-wall panel 43, which is on the right side as viewed from the fourth side-wall panel 44. The monitor 13, the lighting fixture 14, and the electrical-equipment box 15 are disposed above the desk 11, in this order from the bottom to the top, along the third side-wall panel 43. The air-conditioner indoor unit 16 is installed on the upper part of the first side-wall panel 41 such that a blow-out port thereof is oriented in the direction of the floorboard 3 and the fourth side-wall panel 44.

An automatic fire extinguisher 20 is attached to the ceiling panel 5. The automatic fire extinguisher 20 has a lid made of a low-melting-point metal that detects a specific temperature. When the lid detects that the atmosphere reaches a predetermined temperature, fire extinguishant is sprayed in the booth 1.

The air-conditioner outdoor unit 17 connected to the air-conditioner indoor unit 16 is installed on the outer side of the second side-wall panel 42, which is located on the left side as viewed from the fourth side-wall panel 44. A vaporizer 18, which vaporizes drain water discharged from the air-conditioner indoor unit 16 and the air-conditioner outdoor unit 17 and discharges the vaporized drain water into the air, and a secondary-drain-water pan 19 are disposed below the air-conditioner outdoor unit 17 in this order in the gravity direction.

The thus-configured booth 1 is assembled in a factory or the like, is transported by a truck or the like, and is installed on the installation surface FL at a predetermined installation site. An example of the installation site is an internal corner of a building frame, which is an example of an exterior space where foot passengers and the user of the booth 1 exist at the same time. The booth 1 is suitable for installation at an internal corner located in, for example, a concourse space or a passage formed between a subway station and the ground.

More specifically, as shown in FIG. 2, the booth 1 is installed such that the third side-wall panel 43 faces a first wall surface X of an internal corner space, and the first side-wall panel 41 faces a second wall surface Y of the internal corner space. By installing the booth 1 in this manner, the air-conditioner outdoor unit 17 disposed on the outer side of the second side-wall panel 42 does not project into the passage, blocking passage of foot passengers (arrow R in FIG. 2) at the installation site of the booth 1.

The booth 1 may be installed at any exterior space, other than internal corners of building frames. In this case, it is desirable that the booth 1 have a rectangular shape overall in plan view with short sides and long sides, have an inner space defined by the side-wall panels 4 and the air-conditioner outdoor unit disposed on the outer side of the inner space, and be disposed such that the surface having the door 45 face a path or a road where the traffic of foot passengers is heavy. By reducing the length of the booth 1 in the depth direction, which is the length of the short sides, the booth 1 can be disposed so as not to project toward the path by a large amount, and thus, not to inhibit the traffic of the foot passengers.

(2) Air-Conditioning System (2.1) Structure of Air-Conditioning System

FIG. 3A is a partial sectional view illustrating the internal structure of the booth 1, as viewed from the front side, FIG. 3B is a side view of the booth 1, and FIG. 3C is a plan view of the booth 1. FIGS. 4A to 4C schematically show air circulation inside the booth 1. FIGS. 5A to 5C schematically show another arrangement example of the automatic fire extinguisher 20 in the booth 1 and air circulation inside the booth 1. FIG. 6 schematically illustrates the structure of the air-conditioner outdoor unit 17. FIG. 7A is a perspective view of the vaporizer 18 and the secondary-drain-water pan 19, and FIG. 7B is a functional drawing showing vaporization of the drain water in the vaporizer 18. FIGS. 8A and 8B illustrate exhaust discharged from the air-conditioner outdoor unit 17 and the vaporizer 18.

The booth 1 according to this exemplary embodiment includes the air-conditioner indoor unit 16, the air-conditioner outdoor unit 17, an air inlet 43A provided in the third side-wall panel 43, on or along which the desk 11, the monitor 13, the lighting fixture 14, and the electrical-equipment box 15 are disposed, and an exhaust fan 30 provided in the ceiling panel 5. An air-conditioning system of the booth 1 includes circulation of cool air or warm air blown from the blow-out port of the air-conditioner indoor unit 16 and an airflow formed by introducing the outside air from the air inlet 43A and discharging the air by the exhaust fan 30.

As shown in FIG. 3A, the air inlet 43A communicating with the outside is provided in the third side-wall panel 43, on or along which the monitor 13, the lighting fixture 14, and the electrical-equipment box 15, which serve as heat sources, are disposed. The air inlet 43A includes a first air inlet 43Aa provided in the outer surface of the third side-wall panel 43, and a second air inlet 43Ab provided in the inner surface of the third side-wall panel 43. The first air inlet 43Aa and the second air inlet 43Ab do not to overlap each other in the side view.

More specifically, the first air inlet 43Aa is provided near the center of the third side-wall panel 43 in the horizontal direction, and the second air inlet 43Ab is provided at a position closer to the fourth side-wall panel 44 than the first air inlet 43Aa is. The air inlet 43A is provided at a position above the desk 11 and at the same height as the monitor 13 in the vertical direction.

As shown in FIG. 3C, in plan view, the exhaust fan 30 provided in the ceiling panel 5 is located near the automatic fire extinguisher 20, on the third side-wall panel 43 side, at a position close to the fourth side-wall panel 44.

Thus, as shown by arrows A in FIGS. 4A to 4C, an airflow is formed, in which the outside air is introduced from behind the monitor 13, which is one of the heat sources, passes near the lighting fixture 14 and the electrical-equipment box 15, which are other heat sources, and is discharged outside through the exhaust fan 30 provided in the ceiling panel 5.

The monitor 13, the lighting fixture 14, and the electrical-equipment box 15, which are the heat sources, are arranged along the third side-wall panel 43 in this order from the bottom to the top in the space. Thus, the heat from these heat sources can be efficiently discharged outside the booth 1.

Furthermore, the blow-out port 16 a of the air-conditioner indoor unit 16 is oriented in the direction of the floorboard 3 and the fourth side-wall panel 44, such that the air blown from the blow-out port does not directly reach the monitor 13, the lighting fixture 14, and the electrical-equipment box 15, which are the heat sources, or the automatic fire extinguisher 20 provided on the ceiling panel 5. With this structure, in the case of fire, the initial heat can reach the automatic fire extinguisher 20, enabling the automatic fire extinguisher 20 to quickly start a fire extinguishing operation (see the dotted area in FIG. 4A), and condensation due to the cool air from the air-conditioner indoor unit 16 is suppressed, thereby preventing a leakage accident.

FIGS. 5A to 5C illustrate another arrangement example of the automatic fire extinguisher 20 in the booth 1. As shown in FIG. 5A, in front view, the automatic fire extinguisher 20 is attached near the center of the booth 1, compared with that in FIGS. 4A to 4C. By providing the automatic fire extinguisher 20 at this position, when a fire occurs at the center of a seat surface 12 a of the chair 12, the fire extinguishant can be evenly sprayed on the origin of the fire, as well as the front-surface (near-side wall) side and the rear-surface (far wall) side of the booth 1, without being sprayed on the air-conditioner indoor unit 16 (see the dotted area in FIG. 5A).

(2.2) Arrangement of Air-Conditioner Outdoor Unit and Vaporizer

The air-conditioner outdoor unit 17 and the vaporizer 18 connected to the air-conditioner indoor unit 16 disposed in this manner in the booth 1 are disposed on the outer side of the second side-wall panel 42, which is different from the third side-wall panel 43 having the first air inlet 43Aa on the outer surface thereof.

As shown by arrows B in FIGS. 4A to 4C, the outside air is taken into the air-conditioner outdoor unit 17, exchanges heat therein, is discharged toward the outer surface 42 a of the second side-wall panel 42, and flows upward along the outer surface 42 a of the second side-wall panel 42.

As shown by arrows C in FIGS. 4A to 4C, the outside air is taken into the vaporizer 18 through a duct 50, and vaporized drain water, which is high-humidity exhaust, flows upward through the duct 50 and is discharged outside.

With this structure, the vaporized high-humidity exhaust does not enter the booth 1 through the first air inlet 43Aa for introducing the outside air.

As shown in FIG. 6, the air-conditioner outdoor unit 17 includes, therein, a compressor 171 that circulates refrigerant (e.g., chlorofluorocarbon) between the air-conditioner indoor unit 16 and the air-conditioner outdoor unit 17, an outdoor heat exchanger 172 in which a refrigerant circulating therein and the outdoor air exchange heat, and an outdoor-heat-exchanger fan 173. The air-conditioner outdoor unit 17 and the air-conditioner indoor unit 16 are connected to each other by refrigerant pipes 174. The outdoor-heat-exchanger fan 173 allows the outside air to pass through the outdoor heat exchanger 172 and to be discharged outside.

As shown in FIGS. 7A and 7B, the vaporizer 18 is a drain-water treatment device including a tank 181, an ultrasonic transducer 182, a fan motor 183, an air inlet 184, an air outlet 185, and a drain connecting part 186. The vaporizer 18 vaporizes, with the ultrasonic transducer 182, the drain water discharged from the air-conditioner indoor unit 16 and the air-conditioner outdoor unit 17 and discharges the vaporized drain water into the air by the fan motor 183, thus treating the drain water produced in the air-conditioner indoor unit 16 and in the air-conditioner outdoor unit 17 during the heating operation.

As shown in FIGS. 8A and 8B, a duct 50, serving as an example of an air passage, is connected to the vaporizer 18. The duct 50 has an outside-air inlet 51 connected to the air inlet 184, through which the outside air is taken in by the fan motor 183 of the vaporizer 18, and an exhaust receiving port 52 connected to the air outlet 185 of the vaporizer 18. As shown by arrows C in FIGS. 8A and 8B, the duct 50 receives the high-humidity exhaust discharged from the air outlet 185 of the vaporizer 18, allows the exhaust to flow upward through the duct 50, and discharges the exhaust to the outside.

Modification

FIGS. 9A and 9B illustrate discharging of the high-humidity exhaust from the air-conditioner outdoor unit 17 and the vaporizer 18 through a duct 50A according to a modification.

The duct 50A according to the modification has the outside-air inlet 51 connected to the air inlet 184, through which the outside air is taken in by the fan motor 183 of the vaporizer 18, and the exhaust receiving port 52 connected to the air outlet 185 of the vaporizer 18. The duct 50A receives the high-humidity exhaust discharged from the air outlet 185 of the vaporizer 18 and discharges the exhaust to the upper side, from an air outlet 53 formed at the top of the duct 50A. As shown in FIGS. 9A and 9B, the high-humidity exhaust discharged from the air outlet 53 of the duct 50A flows upward along a second wall surface Y of an internal corner in which the booth 1 is installed. This structure prevents the air-conditioner outdoor unit 17 from being frozen due to the drain treatment during the heating operation.

The secondary-drain-water pan 19 is disposed below the vaporizer 18 and can store a certain amount of secondary drain water forcedly discharged from the vaporizer 18 when the drain water has accumulated in the tank 181 of the vaporizer 18.

Arrows B and C in FIGS. 9A and 9B show the exhaust from the air-conditioner outdoor unit 17 and the vaporizer 18. The air-conditioner outdoor unit 17 is disposed such that intake surfaces 17 a of the outdoor-heat-exchanger fan 173 and a discharging surface 18 a of the vaporizer 18 from which the vaporized high-humidity exhaust is discharged are located on different planes and such that the exhaust surface 17 b of the outdoor-heat-exchanger fan 173 faces the outer surface 42 a of the second side-wall panel 42.

More specifically, as shown in FIGS. 9A and 9B, the air outlet 185 of the vaporizer 18 is connected to the exhaust receiving port 52 of the duct 50A, and the intake surfaces 17 a of the outdoor-heat-exchanger fan 173 of the air-conditioner outdoor unit 17 face the same directions as the second side-wall panel 42 and the fourth side-wall panel 44 of the booth 1. The exhaust surface 17 b of the outdoor-heat-exchanger fan 173 of the air-conditioner outdoor unit 17 faces the outer surface 42 a of the second side-wall panel 42 with a certain gap G therebetween.

With this structure, the high-humidity exhaust generated by vaporizing the drain water in the vaporizer 18 and the exhaust air discharged from the air-conditioner outdoor unit 17 flow in the direction opposite to the gravity direction, along the outer surface 42 a of the second side-wall panel 42, along which the air-conditioner outdoor unit 17 and the vaporizer 18 are disposed. This structure prevents the vaporized high-humidity exhaust discharged from the vaporizer 18 from entering the booth 1 and also prevents the exhaust air discharged from the air-conditioner outdoor unit 17 from being blown against people nearby.

FIGS. 10A to 10C illustrate the air-conditioner outdoor unit 17 attached to an installation part.

The air-conditioner outdoor unit 17 is located below the center-of-gravity position of the booth 1, which is located at the midpoint of the height from the installation surface FL to the ceiling panel 5 of the booth 1, and is attached to an installation base 60, serving as an installation part, via rubber dampers 61, which are an example of elastic members. The rubber dampers 61 as shown in FIG. 10C are disposed between an installation plate 17 c of the air-conditioner outdoor unit 17 and the installation base 60, at positions S1 and S2 at equal distances from the center-of-gravity position G1 in the gravity direction of the air-conditioner outdoor unit 17, as shown in FIG. 10A.

The center-of-gravity position G1 of the air-conditioner outdoor unit 17 is located near the compressor 171 because the compressor 171, which is heavy, is disposed at the side of the outdoor heat exchanger 172 and the outdoor-heat-exchanger fan 173. Hence, by disposing the rubber dampers 61 on the installation plate 17 c of the air-conditioner outdoor unit 17, at the positions S1 and S2 located at equal distances from the center-of-gravity position G1 in the gravity direction, leaning of the air-conditioner outdoor unit 17 during the operation is prevented, thus suppressing remaining of the drain water during the heating operation. Furthermore, transmission of vibration of the air-conditioner outdoor unit 17 to the booth 1 is prevented.

As shown in FIG. 11, the rubber dampers 61, serving as elastic members, may be disposed between the base 2 of the booth 1 and the installation surface FL to cut off a specific frequency component of the vibration of air-conditioner outdoor unit 17 transmitted to the booth 1.

The foregoing description of the exemplary embodiment of the present disclosure has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Obviously, many modifications and variations will be apparent to practitioners skilled in the art.
